Be itknown that I, GEORGE F. BURTON, a

- citizen of -the United States, residing et Woodlawn, inzthe county of Jefferson and State of Alabama, have invented certain new and useful Improvements in Rotary Airt Compressors; and I ldo hereby declare the following to be e full, clear, and exact descrlption ci the invention, such as will enable others skilled in the artto which it appertains to `make and use the same.

` My invention relates to a rotary air compresser and has for its ob`ects to provide such a machine which shell cient in operation,easyto build, to ut togather, to take apart and'repsir, an which shall be simple in construction and not easy n w to et out of order.

o these ends my invention consists in the combination of parts hereinafter described and particularly ointed out inthe claims.'

Specification o! Letters Patent. i Patented Sept. 22, 1908.." .i .A application med :une 3,1907. seen N.a'17,o9s. i

The shaft 'A is suitably journaled in bearings G, cast integral with, or otherwise secured to, the bedlate H. These bearings G are also with the bearings I, which are eccentric with res ect to the journals of the cylinders C, Whio cylinders are, therefore,

eccentric to the shait'A and the disks D, as y will appear more fully hereinafter. The disks are 'further provided around their periphery with paclring-boxesfJ, which con- -sists of tWo lates K and L slidingly 'oined d) plate M, and ,provide withby the thir flanges N, ell 'ts-clearly shown in Fi s. 5, 6 and 7. Springs O rees the 'plates and L outward avainst t e inner surfaces of the cylinders and rings P extend around the said disks D a short distance from their peripheries, oneach side thereof, andere provided with cut-away vplaces in which the said flanges N iit. The said iianges N and rings? form a joint flush with the innerend surfaces of the cylinders, and thereby constitute an! i air-tight joint with the 'interior Walls of the same, as above stated.,

To one side of each packing-box J the disks D are rovided with openings Q leading behind tle plates K and L and thereby serve to relieve the pressure ci the air upon their upper surfaces, or, inother Words, to counter-balance said borres'and leave the seme under the control of the springs O. B thus balancing the pressure on the plates and L, I am enabled tokeep the jriction of the same against the interior cylinders under ab- 'sov solute control, and also to regulate to a' nicety the'ttightnessof the packing against necessary to do is to adjust the tension ofthe said sprin O.

The disss D are provided wlth inlet orts R for the air and outlet ports S the atter registering with the ports B in the shaft A. The ports S are controlled by the springpressed valves U seating agalnst tlnmb es the interior of `the cylinders; for-all that it is screwed into or otherwise' secured to the' disks D, the. ressure of said ,valves being controlled by t at in 'the reservoir.

A represents shells surrounding the `cvlin v ders C and 'constitutin the outer Wellsof water-j ackets between t e same and said cylinders.

These water-jackets B are not m-'y Y i i tended to hold a great deal of Water, andere open tQJth'e 'atmosphere at C', Vas shown. ,T

le centrifugalforce is depended vupon. to carryt'he'water to the outer rims of the cylin-l ders and to'hold it there as lon(Y as'the conipressor is operating, or until discharged through the outlet C'. 'By thus keepin the water jackets open to the atmosphere, not only 'get the advantagcsof readily filling and emptying the ackets and alsoof ein loying a small quantity of water; but, at tiesame time, since the water is kept in violent circulation, and by centrifugal action is forced out against the containing Walls of the casings the air is lcft free access to the interior of the vjackets through the openings C'. The air thus enterin r theseo enings,naturally'takes up more, or ess, of t ie motion of the Water,

and cylinders; and therefore, circulates in, and ou t, of said openings; thereby servi-iig to convey away some of the heat impartei to 'the water, and therefore to keep down the tem erature.

E is an inlet for the water.

Ff represents oil reservoirs which deliver oil through the pipes G to the conical openings L in the bearings G and journals M of the cylinders. In operation centrifugal force will carry the `oil inward through said conical o enings and force it outward to the parts of t emachine.

H represents inlets through which the air is taken from the outside and delivered to the cylinders, and said openings or apertures just mentioned forni a continuation of the saine.

The operation of my device is as follows Upon power being applied to shaft A., the same, together with the disks D and cylinders C, revolve.

thereto, as above describedJ the space shown in Fig. 2 between the cylinders and the disks is rapidly diminished as the shaft revolves, and therefore the air is compressed. When thepressure gets to a point suliicient to open the valve U, the said valve permits the air v to escape through the ports S and B into the shaft A, and is thence delivered to the reservoir or point of use. As the disks revolve, .the pistons F, of course, are carried with the cylinders and, therefore, tend to create a -vacuuin behind the same, which causes the air to rush in from the outside through the inlet ports H', the apertures L and the orts R in the disks, as above stated. This air thus sucked in as the shaft continues to revolve, is in turn compressed, as above described, and delivered to the point of use, whenever the pressure there maintained `ermits the valve U to open, and so on, as lling as the compressor is operated.

Z represents a plug in the cylinder C, through which the valve U may be adjusted or repaired. Y 4

The cylinders are placed at 180 degrees n The disks being concentric with the shaft and the cylinders eccentric plates together, sai

from each other and,'therefore, the {delivery} v 4 "of air to the shaft A is always kept at a sub,-

stantially uniform rate.

It will thus be seen that my machine is ex- .-A l I i ccedingly simple, is easy to assemble .and dis-l assemble, that the packing between the piston and disk and the cylinder and disk is also simple and not easy to get out of order, and that there are no irregularly shaped parts, so that the whole compressor can be easily built by machinery.
